Title: Incinerating method of rubber scrap
Inventor: FUJIMURA MASASHI
IPC: F23G5/027
Filed: 1983-05-10
Abstract: PURPOSE:To form chlorine and sulfur in a rubber material into a harmless massive material, by incinerating rubber scrap through presence of a lime in the rubber scrap. CONSTITUTION:10-150pts. based on 100pts. of rubber content in rubber scrap, of a lime is mixed. Rubber scrap, containing the lime, does not need further addition thereof, and in case rubber scrap is slightly short of the lime material, only the short amount is added. Thereafter, the rubber scrap is dry-distillated in a dry distillating furnace 11, the high temperature combustion gas so produced is burnt in a secondary combustion furnace 21. Chloride and sulfur in a rubber raw material react with the lime to produce plaster and calcium chloride, resulting in a harmless massive material, and are removed in a combustion residue containing chamber 17 togetherwith combustion residue.

Abstract: PURPOSE:To remarkably decrease the invasion of leakage magnetic flux to a tank or the like at the peripheral center of the exterior of a core window approached nearest to the coil by increasing the width of the exterior of the core window of a magnetic clamp larger than that of the interior of the core window and projecting it externally from the outermost diameter of the coil. CONSTITUTION:Annular magnetic clamps 12, 13 mounted between core yokes 2, 3 and coils 6, 7 have width at the exterior of the core window wider than that of the interior of the window, and are projected at the peripheral center of the exterior of the window from the outermost layer of the coils 6, 7 toward a tank 8. Accordingly, it is constructed that the area confronting the coil is increased at the exterior of the core window not covered with the core leg 1 and the yokes 2, 3. Thus, most of leakage magnetic flux flowed from the coils 6, 7 is attracted to the clamps 12, 13 projected from the coils as shown by dotted line indicated by the arrow. Consequently, the invasion of the leakage magnetic flux to the tank in the vicinity of the peripheral center of the exterior of the iron window approached nearest to the coils 6, 7 apprehended by loss concentration or local overheat can be largely decreased.
